In plain words
Action is never brought off by one factor alone, and the fruit it yields stands apart from it. Knowledge is the reverse on both counts. So the analogy between them does not hold.
Close to the Sanskrit
Because of action's not being accomplishable by a single factor, and because of the otherness of its fruit — knowledge being the opposite of that — therefore the analogy would be ill-matched.
